Carcharodontosaurus

Carcharodontosaurus, was an enormous theropod dinosaur native to Africa 100 - 93 million years ago during the late Aptian to early Cemonian periods of the Cretaceous. Despite being poorly known, Carcharodontosaurus is likely one of the largest species of theropod dinosaur, larger than Tyrannosaurus, but smaller than Spinosaurus. Two species of Carcharodontosaurus are currently known. C. saharicus is the type species, while C. iguidensis is smaller.

Very little is known about Carcharodontosaurus and Carcharodontosaurids in general. The Holotype of Carcharodontosaurus, discovered in 1912 by Stromer along with Spinosaurus. After describing Spinosaurus, he described another large Theropod which he dubbed 'Spinosaurus B'. It was not until the 1930's when more fragmentary remains, albeit sub-adult, was it realised this 'Spinosaurus B' was actually very different from Spinosaurus, and so Stromer re-named it (and Megalosaurus saharicus in the process) Carcharodontosaurus saharicus, meaning "Saharan shark-toothed reptile".
